ROADHSCRAPER.

SPECIFICATION forming part of Letters Patent No. 398,581, dated February26, 1889.

Application led September 24, 1888.

To all 'whom t may concern:

Be it kno'wn that I, ELIAS BURHANCE, a citif zen of the United States,residing at South Kent,in the county of Litchfield and State ofConnecticut, have invented certain new and useful Improvements inRoad-Scrapers; and I do hereby declare the following to be a full,clear, and exact description of the invention,

i l i i i l l such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to diggers and scrapcrs generally, but is moreespecially adapted to the class of scrapers used in building` and 1novel construction ol' which the following dcscription, in connectionwith the accompany ing drawings, is a specification, numbers being usedto denote the several parts.

Figure 1 is a plan view of the machine complete; Fig. 2, a sideelevation as seen from the left, and Fig. 3 a side elevation as seenfrom the right.

l'denotes the framework, which preferably consists of two pieces only,lying at an acute angle to each other, as shown in Fig. 1. The parts ofthe framework are rigidly secured to the rear axle, 2, and to a block,3, resting I i sition. The operator is thus given perfect on the frontaxle, 4.

5 denotes the scraper, which is ordinarily made of wood, and is providedat its lower edge with a cutting-blade, G, preferably7 made The scraperis supported at an oblique angle to the line of tra-vel of the machineby means of braces 7, three being ordinarily used, the front ends ofwhich are pivoted to the scraper and the rear ends to the rear axle.

8 denotes an arm projecting' upward from the scraper, the upper end ofwhich lies between diagonal braces 9, extending between the two parts ofthe frame-work, and islockcd in any desired position by means of pinsl0, passing through both braces, a number of transverse holes being madethrough the Serial No. 286,280. (No model.)

braces, so that the scraper may be locked at any desired angle to theplane of the roadway. Should it be desired to have the scraper operatein a. plane vertical to the plane of the roadway, arm S is moved to avertical position and locked there by means of pins l0. Should it bedesired to have the scraper operate in a plane at a more or less acuteangle to the plane of the roadway, arm S is moved backward and locked aithe desired position by the pins.

ll. denotes a cross-piece rigidly secured to the framework obliquely tothe line of travel and approximately parallel with the scraper.

12 denotes levers pivoted to th scross-piece, and 13 rods connected tosaid levers and to the scraper near the ends thereof.

la denotes a platform at the rear end of the machine, upon which anoperator stands and controls the action. of the scraper by means oflevers l2. Should it be desired to raise the forward end of the scraper,the lever upon that side is raised. Should it be desired to raise therear end of the scraper, it is accomplished by raising the other lever.The rear ends of the levers lie between pairs of up rights 15, and maybelocked in any desiredV position by means of pins 1G, passing throughthe uprights between which the levers rest. It will thus be seen thatthe operator is able to adjust the angle at which the scraper acts atwill, and to lock it in position, and also to adjust the height ofeither end of the scraper at will, or to raise the entire scraperbymeans of the levers and to lock it at any desired pocontrol of thescraper without stopping the machine, this being a very valuablefeature, particularly where there are obstructions to the continuousoperation of thc scraper in l any special position.

17 denotes a seat for the" driver, which is secured to the frame-work inany suitable manner; and 18, a footerest.

19 denotes the front wheels, and '20 the rear wheels. lt will be noticedin Fig. 1 that the rear axle is considerably longer than the front axle,and that the rear wheel corresponding with the rear end of the scrapertracks with the front wheel upon the same side. It will ot' course beapparent that in use the forward end of the scraper will producesomething of a furrow-that is, there will be an abrupt ridge of earthleft at its edge. It is an important feature of my invention that Iplace the rear wheel upon that side directlyin line with the I'orwardend oli' the scraper, so that said rear wheel will track in the furrowmade by the scraper, and will be supported by the shoulder or ridge ol'earth lel't just outside the line ot action of the scraper.

It will be understood by those familiar with this class of machines thatin use the tendency is for the rear portion of-the machine to workinward, so that the earth collected by the scraper is not deposited atthe desired position. lnorder to overcome this tendency as much aspossible the machines have heretofore been made very heavy, thus greatlyincreasing` ythe draft and rendering it impossible for them to beoperated to any extent by a single team. This objection is whollyovercome in my improved scraper by causing the rear wheel upon that sideto track in the furrow left by the forward end of the scraper. The outerside of this wheel, thereto re, in pract-ice bears against the solidridge ot' earth, so that the tendency to slide in that direction iswholly overcome and the earth collected by the scraper is deposited atjust the desired position. This is a great saving in the bnilding ofroads, as it avoids a repetition of operations to accomplish the dfsredresult, while at the same time the draft ot the present machine is somuch lighter than any heretofore produced capable of performing the sameamount of work as to make a still more l l l i l, i' l l l importantsaving in the amount of draftpower required.

It should be understood that I do not limit my invention to the exactdetails of construction shown and described, as it is obvious that thedetails may be greatly varied without departing from the principle of myinvention.

l claiml. The t1'aine-worl ,tl1e scraper placed obliqu'ely thereto, afront axle and wheels, and a rear axle and wheels, one rear wheel beingin line with the corresponding front wheel and the other rear wheel inline with the forward end ofthe scraper, in combination with diagonalbraces 9, an arm, 8, projecting` from the scraper, whereby the angle maybe adjusted, and levers l2 and rods 18, connecting said le` vers withthe opposite ends of the scraper, whereby either end may be raised orlowered.

2. The scraper having an arm, 8, the rear axle, and braces pivoted tothe axle and to the scraper, whereby the latter is supported, incombination with frame-Work, diagonal braces 9, between which the armlies, and pins passing through sai d braces, whereby the arm may belocked in posit-ion to hold the scraper at any desired angle.

In testimony whereof I affix my signature in presence of two witnesses.
